Publication A Study of Trauma Patients in the Emergency Department of a Tertiary Care Hospital in Nepal during Lockdown in COVID-19 Pandemic(Kathmandu University, 2022) Shrestha, SK; Dahal, S; Bhattarai, AABSTRACT Background The nationwide lockdown was imposed upon by the Government of Nepal with regards to the COVID-19 pandemic. Even during times of limited mobility and travel, trauma cases were presenting to the hospital. Objective To asses trauma patterns among patients presented to the Emergency department in Dhulikhel hospital during the lockdown period. The assessment of the burden of trauma during the pandemic could aid in planning allocation of resources and improving trauma care. Method A retrospective cross-sectional study design was used to assess all patients with a history of trauma during the period of lockdown announced by the Government of Nepal for COVID-19 from March 24 to June 14, 2020. Result Among 2097 patients that visited the emergency department, 23% were trauma cases. In comparison to the corresponding time-period in 2019, trauma cases reduced by more than half (54.5%). The majority of patients utilized ambulances as a means of transportation; a few patients utilized Dhulikhel emergency medical services. The most common mechanism of injury was fall injury, followed by motor vehicle accident and physical assault. Traumatic brain injury occurred in 30% of patients. Of all patients, 71% were discharged after initial treatment, 26% were admitted to different wards and 3% were referred to other health centres. Conclusion Fall injury is a crucial public health concern followed by motor vehicle accident among trauma patients even during the pandemic condition. Thus, emergency rooms should aid in planning for preparedness, mitigation of trauma during situations like these, in planning the allocation of resources and improving trauma care.

Objective To determine the role of predictors for Obstructive sleep apnea syndrome and its severity in Nepalese population. Method Prospective and analytical study conducted in the Department of Otorhinolaryngology and Head and Neck surgery at Kathmandu University Hospital between March 2018 and June 2020. A total of 85 adult patients with Obstructive sleep apnea with an Epworth sleepiness score greater than 10 were included. Overnight polysomnography was done and scoring of sleep associated events were done according to the American Academy of Sleep Medicine criteria. Participants were classified as simple snoring and mild, moderate or severe Obstructive sleep apnea syndrome groups depending on the Apnea Hypopnea Index values. Relationship of Apnea hypopnea index was analyzed with age, neck circumference, body mass index and Epworth Sleepiness score. Result Simple snoring was seen in 18(21.17%) patients, 14(16.47%) had mild Obstructive sleep apnea, 13(15.29%) had moderate Obstructive sleep apnea, whereas the severe group consisted of 40(47.05%) patients. The minimum Epworth Sleepiness Score was 10 and the maximum was 25. The Apnea hypopnea index correlated positively with Body mass index (p=.010) and Epworth sleepiness score (p<.001). However, Apnea hypopnea index had no association with age (p=.437) and neck circumference (p=.118). Conclusion Health professionals need to be extremely vigilant while examining patients presenting with Obstructive Sleep Apnea. Polysomnography is the investigation of choice in the early identification of this treatable disease.

Although controversies exist regarding the most efficient technique, till now the best entry technique is still unsettled. Objective To compare the safety, operating time and outcome of Direct Trocar Insertion with a well-established and widely practised Open Access Technique. Method This is a prospective study at Nobel Medical College Teaching Hospital from November 2019 to February 2021. Patients were grouped into either of the two groups, Group 1 for Direct Trocar Insertion and Group 2 for Open Access Technique. They were later analysed for major and minor complications of the technique and a comparison of either method was done at the end of the study period. Result A total of 823 patients were enrolled in the study. Among the study population, 411 patients had Direct Trocar Insertion while 412 patients had Open Access Technique. The majority of the operation that was done during the study period was laparoscopic cholecystectomy. Patients in the Open Access Technique group experienced more complications compared to Direct Trocar Insertion group. Conclusion Despite the fear of adopting the Direct Trocar Insertion, this is a safe, better and quick technique for laparoscopic port entry. However, any surgeon practising laparoscopic surgery should be competent to adopt either technique to overcome failure in either process during port entry.

When such changes are recorded in lab as biological signals, induced with appropriate stimulus, the observed response may serve as a good indicator of homeostatic alteration. In this study, skin conductance was utilized to record sympathetic response for cognitive load, by application of simple subtraction task. Objective To detect sympathetic arousal by utilization of galvanic skin response during mental arithmetic task. Method Total of eighty two subjects, forty two female and forty male participated in the study. Twenty two subjects were provided mental task to record skin conductance. In sixty subjects, galvanic skin response, pulse rate, respiratory rate and temperature were recorded by appropriate transducers to obtain baseline and task response to detect differential recordings. Subjects performed the mental exercise of arithmetic task (MAT) with transducer placed in upper limbs. Mean of averages for respective variables were statistically calculated from obtained recordings. Result For measured galvanic skin response, 57 subjects showed increased skin conductance (rise in amplitude) whereas, 25 subjects had no rise in amplitude (“A peak”) while performing the mental arithmetic task, when compared to control recording. However, in 20 subjects, pulse rate and respiratory rate showed significant rise though, the change in the skin conductance was not significant. Conclusion Galvanic skin response is useful for demonstration of sympathetic activation induced by simple mental subtraction task, and can be utilized along with vital parameters mentioned in this study to discuss in vivo variation that exist as differential for core and superficial sympathetic outflow among individuals.

Other endogenous pathologies include mucous plugs and polyps. Foreign bodies of Wharton’s duct and submandibular gland are rare. Retrograde migration of foreign bodies via ductal orifice, traversing the ductal system to its final intraglandular location is an even rare entity. These often present with painful swelling of the gland and at times with a purulent sialitis. Diagnostic modalities include plain radiography, ultrasonography, sialography, as well as computed tomography and magnetic resonance imaging. Treatment includes antibiotics, incision and drainage of abscess, and removal of foreign body either surgically (intra-oral approach or sialadenectomy) or more recently via sialoendoscopy. This is a case report of 30 years male with accidental cannulation of Wharton’s duct with grass that eventually got lodged in the deep lobe of the gland, and was managed with sialadenectomy.

Myiasis denotes maggot infestation in living tissue. There are two forms of myiasis namely obligate and facultative. Obligate myiasis denotes maggots feeding on living tissue whereas facultative myiasis represents the opportunistic behaviour of the fly taking advantage of wound or necrotic tissue, laying by eggs which hatch into maggots. Decreased physical activity and poor hygiene leads to maggot infestation. Maggot invasion of living tissues is undesirable occurrence which can best be avoided by improving hygiene. People with low living standards in the developing nations are the occasional victims for maggot infestations. We present cases of obligate myiasis for their uniqueness and rarity.

Approximately 40% of the alveolar subtype occur in the head and neck region. Patients present with unilateral nasal mass with/without lymphadenopathy and with/without orbital manifestations. Diagnosis is aided radiologically by CT scan, MRI along with biopsy and is confirmed by immunohistochemistry. Treatment involves surgical resection, chemotherapy, radiotherapy or a combination of these. In spite of treatments, however, the outcome is poor. This is a case report of 14-year-old male who presented with unilateral nasal mass with proptosis of right eye who was eventually diagnosed as a case of alveolar rhabdomyosarcoma of solid variant. KEY WORDS Alveolar rhabdomyosarcoma, Immunohistochemistry, Nasal cavityPublication Thresholds for Spinal Anaesthesia-induced Hypotension During Caesarean Section(Kathmandu University, 2021) Gautam, B; Bhattarai, AABSTRACT Background Spinal anaesthesia is the current standard for caesarean section. Hypotension, a common complication, potentially results in adverse foetal and maternal outcomes. However, hypotension-defining criteria are varied. Objective To identify the blood pressure thresholds for spinal anaesthesia-induced hypotension during caesarean section. Method This is a retrospective cohort study of spinal anaesthesia-induced hypotension that occurred till baby-delivery during caesarean section. Reports on intraoperative hypotension, collected previously from January to December 2019, were reviewed to identify the hypotension-defining thresholds. The thresholds were categorized into systolic blood pressure (SBP) of 80, 90 or 100 mmHg, mean arterial pressure (MAP) of 60, 65 or 70 mmHg, combinations, and others. Parturient and anaesthesia characteristics, and associated hypotensive symptoms were also recorded for descriptive analysis. Result Spinal anaesthesia-induced hypotension was identified in 129 (11.5%) cases among 1116 caesarean sections. Altogether, 12 hypotension-defining thresholds were employed. Thresholds of SBP 90, MAP 60, and SBP 80 mmHg were used in 53 (41%), 28 (21.7%), and 21 (16.2%) cases respectively. Mean maternal age was 28 (±4.22) years and 87 (67.4%) cases underwent emergency surgery. Median sensory blockade level was T4. Nausea-vomiting, bradycardia, and tachycardia were associated during five (3.8%), six (4.6%), and 15 (11.6%) hypotensive incidents respectively. Two cases had unrecordable blood pressure but there was no maternal mortality. Conclusion Systolic blood pressure of 90 mmHg and mean arterial pressure of 60 mmHg included the most common thresholds for spinal anaesthesia-induced hypotension during caesarean section. Identifying the safe and clinically relevant hypotension-defining criteria needs further investigation.

Majority of patients can be discharged safely after reassurance while a fraction of patient requires observation and further management. Here we report a case of a 35-year-old gentleman who presented to the out-patient department of our hospital in June 2021 for accidental ingestion of toothbrush. After detailed history and physical examination upper gastrointestinal endoscopy was planned for the patient. Failed endoscopic removal was considered the indication for surgery. A supraumbilical midline incision was used to remove the toothbrush. Following the surgical removal, he was managed conservatively and was discharged without significant complications. We describe this case in detail in addition to reviewing the pertinent literature. KEY WORDS Endoscopy, Foreign body, Surgery
